Following the publication of preliminary maps of flood zones based on Quebec’s new regulatory framework, the City of Longueuil considers itself still safe from river flooding.
Longueuil, within its agglomeration powers, indicates that it was consulted and participated in the development of the preliminary mapping unveiled by the Montreal Metropolitan Community. “As this guide could still be modified, the preliminary maps are not final and they could be slightly different. The City will therefore follow the progress of the work surrounding the preparation of flood zone maps and the adoption of the new regulatory framework,” she maintains.
Safe city and town
The City points out that its territory is relatively protected from river flooding, being located downstream of the Mille-Îles and Outaouais rivers. The City was not affected by the significant flooding due to the rising waters that affected the west of the metropolitan region in recent years. “The only small plots of flood zones are located in Marie-Victorin Park,” information already known to the City, it is reported.
The territory of the agglomeration is also not very sensitive to river flooding, being located downstream of large rivers and largely protected by the dike of the St. Lawrence Seaway.
Sectors targeted
Two sectors are covered in the map, that of the Saint-Jacques River, located between the territory of Brossard and La Prairie, and another sector in the territory of Boucherville, around the Rivière aux Pins. These maps were established according to the terms of the methodological guide produced by the government in order to visualize the repercussions of the regulatory framework on the territory of the CMM.
Data integration
Now that the detailed maps are available, the cities of the agglomeration will be able to assess the potential repercussions for their territory. “Ultimately, it is specified, the final mapping and the regulatory framework will be integrated into the planning and development plan for the Longueuil agglomeration.”
“The City’s main concern in terms of flooding remains those caused by torrential rains linked to climate change,” concludes the City.
